The Students in this Honors Biology class will perform an independent research project upon the completion of our
Botany Unit. The objective of this project is to study the necessity of light and chlorophyll for Photosynthesis. We will be using
Geranium plants with leaves exposed to light or covered with aluminum foil. A positive control plant will be placed in full sunlight.
The negative control plant is placed in the dark.
The production of starch is used to detect Photosynthetic activity. An iodine test for starch is performed after
an ethanol chlorophyll extraction. The project duration is 7 days.
Students will bring cameras, either their own cameras or a school camera to lab class.
Each team is to write a script to explain their experiment. Your finished product will be an audio lab report.
Using the script each team is to take pictures of their geranium before and during the experiment or of the aspect of the experiment you would like to explain. Take one picture of your group to use as your opening to introduce your experiment.
All pictures will be download to the server and then upload to your voice thread. Set you voice thread to be public with comments. When you finish recording you will reset your voice thread to be public with no comments.
Attach the headset with microphone to your computer. Go to the system preferences under the apple to sound and select logic tech headset for both input and output.
Using the analysis questions furnished by Mrs. Haughton you will identify various aspects of your experiment. Don't forget to use the doodling tool to as you record your voice to point to the elements you are explaining. When you finish you will have an audio lab report
When you are finished remember to change your voice thread to public with no comments and to give your title to Ms. Haughton.
Through this lab assignment you will have the opportunity to present your lab report in a different and fun format. You will become knowledgeable in photosynthesis and also hone your technology skills as you become familiar with one of the newest web 2.0 collaboration tools, Voice Thread.
